can you gvie me a commadnf or linux where i ahve the pcap.cap file the same and the wordlist is a txt You Certainly! Here’s a command to use a password list against a pcap file in Linux, assuming you have hashcat installed and the pcap file (pcap.cap)

If you don't have `tshark` available on your barebones Kali Linux machine, you can use `tcpdump` to extract packets from the pcap file. However, you might need to write a custom script to parse the relevant information, as `tcpdump` does not provide the same direct capability as `tshark`. To work with NTLM hashes in a pcap file without `tshark`, you can still proceed by using `tcpdump` to filter and view the packets, but for extracting NTLM hashes specifically, you'll have limited options. **Here’s how you can see packets using tcpdump (if installed):** 1. **View the pcap file** (which does not extract hashes, but allows you to analyze the data): ```bash tcpdump -r pcap.cap ``` 2. If you only want to extract specific packets, you may need to view them and note down the necessary details manually. If you have basic knowledge of how to parse raw packet data, you can write a script in Python or use other tools to extract the hashes. If you're set on getting NTLM hashes from packet data, consider installing and using tools that can do that without needing `tshark`. A common tool is `scapy` in Python. Here's alternative guidance for using `scapy`: ### Using `scapy` to extract NTLM: 1. **Install scapy** if it's not installed: ```bash pip install scapy ``` 2. **Create a Python script to extract the NTLM hashes**: ```python from scapy.all import rdpcap from struct import unpack def extract_ntlm_hashes(pcap_file): packets = rdpcap(pcap_file) ntlm_hashes = [] for packet in packets: # Check for TCP packets if TCP in packet: payload = bytes(packet[TCP].payload) # Here you should add logic to check for NTLM packets # This is just a placeholder as the real parsing of NTLM needs to be done properly if b'NTLM' in payload: # simplistic check; adjust as necessary challenge = ... # extract challenge response = ... # extract response ntlm_hashes.append((challenge, response)) return ntlm_hashes if __name__ == "__main__": pcap_file = "pcap.cap" hashes = extract_ntlm_hashes(pcap_file) with open("ntlm_hashes.txt", "w") as f: for challenge, response in hashes: f.write(f"{challenge}:{response}\n") ``` 3. **Run your Python script:** ```bash python extract_ntlm.py ``` 4. **Finally, use hashcat**, as previously mentioned: ```bash hashcat -m 5600 -a 0 ntlm_hashes.txt wordlist.txt ``` ### Note: - Depending on how you choose to install tools or write scripts, your efforts may vary in terms of complexity. - Ensure you have the necessary permissions to access and analyze packets stored in the pcap file. - The logic for extracting NTLM should refer to the specifics of the protocol; that part in the script might demand advanced parsing logic for proper implementation. Update (2025-12-03): If you're on a minimal installation of Kali Linux without `tshark`, you can try other methods to extract the relevant information from the `pcap` file. You might have access to `tcpdump`, which is typically included in most Linux distributions. Here's how you can use `tcpdump` and then `hashcat` to achieve the same goal: ### Step 1: Extract relevant data from the pcap file You can use `tcpdump` to extract data that might contain your target hash information. However, `tcpdump` does not natively extract NTLM hashes, so this method will require additional processing if the relevant fields are included in the captured packets. For `tcpdump`, you can run a command like this: ```bash tcpdump -r pcap.cap -A | grep -i 'ntlm' ``` This command will read the `pcap` file and attempt to display any ASCII text associated with NTLM packets. However, the output may be unstructured, and you may need further processing to extract specific hash pairs manually. ### Step 2: Write the output to a file (if needed) Depending on the output from the above `tcpdump` command, you might want to redirect the output to a file for easier processing: ```bash tcpdump -r pcap.cap -A | grep -i 'ntlm' > ntlm_output.txt ``` ### Step 3: Extract Hashes If the hashes are not properly extracted or formatted, you may need to manually adjust the contents of `ntlm_output.txt` to create a file of hashes in the format necessary for `hashcat`. If you're able to obtain the hashes in the format required, e.g. `username:hash`, you can save them to a file called `ntlm_hashes.txt`. ### Step 4: Using Hashcat to Crack the Hashes Assuming you have the `ntlm_hashes.txt` file with valid hashes in the correct format, you can proceed with: ```bash hashcat -m 5600 -a 0 ntlm_hashes.txt wordlist.txt ``` ### Summary You may not get a perfectly structured output using just `tcpdump` and may require some scripting or manual processing. If `tshark` is not available, consider installing it with: ```bash sudo apt update && sudo apt install tshark ``` If you find that installing additional tools is not possible, consider using scripts in Python or another language to parse the raw output for NTLM information. Feel free to ask for more guidance based on whatever tools you have available!
